Bols, P.E.J. et al Theriogenolgy 1996; 45:1001-4
OSMOLALITY
OSMOLALITY is themeasure of solute
particles dissolved in a solution
as calculated by an osmometer expressed
as milliosmoles / kilogram (mOsm/kg)
OSMOLARITY is the measure expressed in
milliosmoles / litre (mOsm/L) and is less
accurate as calculated in terms of
solvent volume The difference depends
on how the concentration was derived.
Solute concentration can exert osmotic
pressure –
impacting on cell volume and stressing

STEAM:
Vapour steam cleanersor steam vapour systems are cleaning appliances or devices that use steam to quickly
dry, clean, and sanitize inanimate surfaces. Often the process is effective enough to disinfect or even sterilize
the surfaces. The steam is produced in a boiler that heats tap water to high temperatures (240-310F/115-
155C) to produce low-pressure (several atmospheres), low moisture (4 to 6% water) water vapour (steam).
The steam's ability to clean is based primarily on its heat. The steam is applied to cleanable surfaces via a
variety of insulated tools and accessories, thereby safely providing the energy needed to break soil bonds and
release contaminants into water suspension, after which they can be removed by wiping or vacuuming.

SEEING SPERM
• Takingthis into account, the Tel Aviv
University scientists developed a
technology allowing scientists to perform
clinical sperm analysis without the use of
staining.
• new device, a black box that is attached
to a microscope and joined to software,
harnesses phase imaging methods to
assess the quality of sperm
• new tool is small, cost-effective, and
easier to use than conventional
interferometric imaging methods and so,
he believes, it will lead to greater success
when using ART treatments
59.
Spermobikes:SPERMBOTS
“
Low motility” problems,when healthy sperm just can’t swim, are one of the main causes of
infertility. To give slow swimming sperm a helping hand, the German science team developed
a unique solution: the Spermbot
Based on previous work with micromotors, the researchers constructed mini-metal motorized
helices just large enough to fit around the tail of a sperm. Using a rotating magnetic field as the
joy stick, the researchers can direct the micromotor helices to slip around a sperm cell, to drive
the sperm to an egg, and then to release the sperm for potential fertilization. Essentially, the
spermbot serves as a power motor.
60.
Laboratory Advancements and
Innovation
InVitro Maturation (IVM)
• The ability to mature oocytes in a laboratory environment, in vitro
maturation (IVM), is another innovative technology that is being
currently perfected by many centers.
• IVM, as currently described, is the practice of retrieving immature
human oocytes which then complete the transition from prophase
I to metaphase II, including extrusion of the 1st polar body, in
vitro
• The benefit of IVM in today’s current clinical environment is
unclear and will need to be further explored

Reproduction. 2008;136: 703–15
61.
Laboratory Advancements and
innovation:Cryopreservation
• Perhaps the most significant innovation in
embryologic laboratory technology in recent
years has been in the field of cryopreservation
• Applying cryopreservation to IVF embryos was
achieved relatively early in 1983 when the first
pregnancy resulting from a cryopreserved
embryo was reported
• The process used to cryopreserve embryos has
evolved since this time and many innovations
have been done in this field.
Shufaro Y, Schenker JG. Cryopreservation of human genetic material. Ann N YAcad Sci.
2010;1205:220–4.
62.
• oocyte cryopreservationprotocols using
vitrification, including the introduction of the
equipment innovations such as the cryotop, have
been continuously optimized
• These techniques resulted in oocyte survival rates
following cryopreservation approaching 90 % by
2005
• . Currently, multiple clinics report pregnancy rates in
cycles utilizing oocyte cryopreservation that
approach those seen in fresh IVF cycles
• However, the practice of oocyte cryopreservation is
still considered an experimental technology
according to the American Society for Reproductive
Medicine (ASRM)
63.
• The demonstrationthat oocyte
cryopreservation is now a viable
alternative to embryo
cryopreservation has broad
implications. The application of
this technology that could
impact the largest proportion
of society is for women who
wish to preserve their fertility.
Women who pursue professional
careers are increasingly delaying
childbearing compared to historical
normsBroekmans FJ, Soules MR, Fauser BC. Ovarian aging:
mechanisms and clinical consequences. Endocr Rev.
2009;30(5):465–93.
64.
Fertility presevation incancers
• Oocyte cryopreservation has additional
applications that are currently being utilized
• Oocyte cryopreservation is increasingly being
offered as a method of fertility preservation for
oncology patients prior to receiving chemo or
radiation therapy
• Cryopreservation of unstimulated ovarian
cortical tissue for the purpose of fertility
preservation for oncology patients has also been
performed, although with limited success
65.
• As donoroocyte cycles currently
comprise approximately 10 % of
all IVF cycles, egg banks, from a
systems point of view, represent
a significant innovative advance
in quality and efficiency
66.
Innovative EGG BANKS
Anotherapplication for oocyte cryopreservation is the recent
creation of donor oocyte
“egg banks”
for use in donor oocyte cycles. Traditionally, donor oocyte
cycles demanded that the cycles of the donor and recipient be
coordinated. Egg banks eliminate the need for this time
consuming and costly process while offering increased choices
to couples undergoing a donor oocyte IVF cycle
INDIA HAS EGG BANKS : YES, MOST OF
US
NOW ARE DOING EGG BANKING IN

Innovations inTechnologies Evaluating
Embryos
•Traditionally, embryo morphology has been the most
utilized method of determining embryo quality.
• There are numerous grading systems that have been
developed to grade embryo morphology .
• However, embryo morphology alone has been shown
to be a suboptimal indicator of determining which
embryos have normal chromosomal status (euploidy)
or optimal implantation potential .
• For this reason, a variety of different modalities have
been developed to evaluate embryo quality both
directly and indirectly.
68.
Technologies Evaluating Embryos
PreimplantationGenetic Diagnosis
(PGD)& (PGS)
• Preimplantation genetic diagnosis (PGD) and
preimplantation genetic screening (PGS)
involve obtaining one or more cells from the
developing embryo and evaluating the genetic
composition of this cell(s) for either a specific
genetic defect known to exist in the parents
(PGD) or to screen for the presence of embryo
aneuploidy (PGS)
Reproductive choices forcouples at
genetic risk
• No testing
• No children
• Adoption
• Donor egg/sperm or embryo
• Prenatal testing: CVS or
amniocentesis
• Preimplantation Genetic Diagnosis
(PGD)
72.
Which IVF unitshould offer PGD?
• Before offering PGD, the IVF clinic needs to
ensure that it has a good IVF pregnancy rate
• Pregnancy rate following PGD is lower than
general IVF pregnancy rate –
– Potential impact of biopsy procedure - Less cycles
proceed to transfer - Fewer “normal” embryos
available for transfer (may not be possible to select
an embryo with good morphology for transfer)
• To offer PGD to patients, we need to
demonstrate that the benefit of PGD
outweighs the impact of the biopsy procedure
74.
Embryo Biopsy
Polar BodyBiopsy (Day 0-1)
Advantages:
• Less invasive? - Polar bodies have no role in the
development of the embryo
• Biopsy has no detrimental effect on oocyte
fertilisation rates or further embryo development
• Blastomere or blastocyst biopsy available as
confirmation or backup
Disadvantages:
• Restricted to the diagnosis of maternally derived
abnormalities - Paternal abnormalities will go
undetected
• First polar body is often fragmented - Potential for
misdiagnosis based on an inability to recover all DNA
fragments
75.
Embryo Biopsy
Blastomere Biopsy(Day 3)
Advantages:
• Removal of 1-2 cells does not appear to affect
development
• Diagnosis of maternal and paternal abnormalities
• Most frequently performed method of biopsy
Disadvantages:
• Only 1-2 cells available for analysis
• Chromosomal mosaicism in the embryo - Does the
biopsied cell accurately reflect the constitution of the
embryo?
• Embryos typically start to undergo compaction on Day
3
• Removal of a single blastomere can be difficult –
Incubate in Ca/Mg-free media before biopsy
• Rapid diagnosis required for Day 4 or Day 5 transfer
76.
Embryo Biopsy
Blastocyst Biopsy(Day 5/ Day 6)
Blastocyst biopsy has been associated
with:
• Higher implantation rate than Day 3
(regardless of maternal age)
• Lower aneuploidy rate than Day 3
• Reduced mosaicism compared with
Day 3
• More cells available for analysis
• PGS evaluating23 chromosomes and day 5
biopsy has resulted in excellent pregnancy
rates in specific patient populations such as
couples suffering from recurrent pregnancy
loss (RPL) .
• The recent technological advances in
preimplantation genetic testing suggest that
there will be a wider implementation of
PGD/PGS in the future

microarray preimplantation genetic screening (PGS) on blastocysts, versus day-3 embryos,
results in significantly higher clinical pregnancy rates. Fertil Steril. 2011;96 (3):S221.
84.
• Innovations ingenetic medicine are
increasingly linking medical conditions to
specific genetic markers .
• The expansion of genetic medicine in the
future will certainly broaden the applications
of medically indicated PGD.

Technologies Evaluating Embryos:
PreimplantationGenetic Screening
(PGS)
• Chromosomal aneuploidy is believed to be the
single greatest causal factor in pregnancy failure
• PGS is the practice of evaluating cells from a

identifying aneuploidy
• PGS was introduced as a technology that could
greatly improve pregnancy efficiency in IVF
patients at risk for miscarriage such as couples
suffering from recurrent pregnancy loss or
patients with advanced maternal age.

OMICS
• OMICS informallyrefers to a field of study in
biology
• The related suffix -ome is used to address the
objects of study of such fields, such as the
genome, proteome or metabolome
respectively
89.
GENOMICS is theBUZZ word now
• Genomics: Study of the genomes of organisms
• Cognitive genomics examines the changes in cognitive processes associated with
genetic profiles
• Comparative genomics: Study of the relationship of genome structure and
function across different biological species or strains
• Functional genomics: Describes gene and protein functions and interactions (often
uses transcriptomics)

analysis of the Epigenomics: Study of the complete set of epigenetic modifications
on the genetic material of a cell, known as the epigenome. ChIP-Chip and ChIP-Seq
technologies used.
90.
Technologies Evaluating Embryos:
Secretomicsand Metabolomics
• Secretomics and metabolomics offer another
strategy of determining which embryos are
optimal to consider for uterine transfer .
• These technologies attempt to determine
information about embryos from byproducts that
can be measured in the media culture fluid
surrounding the developing embryo .
• One important advantage of these approaches is
that they provide a noninvasive manner to
evaluate embryos versus invasive techniques that
require embryo biopsy.

Lipidomics
• Lipidome isthe entire complement of cellular
lipids, including the modifications made to a
particular set of lipids produced by an
organism or system
• Lipidomics: Large-scale study of pathways and
networks of lipids. Mass spectrometry
techniques are used.
92.
Proteomics• Proteome isthe entire complement ofproteins,
including the modifications made to a particular set of
proteins, produced by an organism or system
• Proteomics: Large-scale study of proteins, particularly
their structures and functions. Mass spectrometry

Proteomics to Develop more suitable
Cryopreservation Conditions
The ability to quantitate developmentally
important molecules may potentially form the
basis for the development of non-invasive
viability assays
93.
Metabolomics
• Scientific studyof chemical processes involving
metabolites. It is a "systematic study of the
unique chemical fingerprints that specific cellular
processes leave behind", the study of their small-
molecule metabolite profiles
• Metabonomics: The quantitative measurement of
the dynamic multiparametric metabolic response
of living systems to pathophysiological stimuli or
genetic modification
94.
• The “OMICS”have been have been of
enormous value in the optimization of
embryo culture and cryopreservation .
• More recently their ability to assist with
the
identification of viable euploid
embryos has
been the focus of great attention.
96.
METABOLOMICS
• Significance ofmetabolism to
embryo development and viability
• Energy is fundamental to the
survival and development of any
cell.
The metabolism of the
preimplantation embryo changes
during development and
• differentiation.
• Loss of metabolic regulation is
associated with poor development
and a loss of viability.
97.

TimeLapse Imaging
• Another recent development
in noninvasive evaluation of
developing embryos is the
use of time lapse imaging and
videography.
• This emerging field offers yet
another technology that, as it
is perfected, may be a
powerful tool to select
embryos best suited for
uterine transfer in IVF cycles.

First Baby BornUsing Innovative Stem
Cell In Vitro Fertilization Technique
• Zain Rajani was born by
taking an ovarian tissue
sample from his mother,
Natasha Rajani. Her tissue
sample was analyzed in
order to identify egg stem
cells. Once the egg stem cells
were identified, they were
removed from the tissue and
purified. The purification
process allowed for the
extraction of the
mitochondria, organelles
that provide energy for cell,
in the egg stem cells. The
introduction of
mitochondria provided a
more reliable source of
energy for the egg cells and
helped produce a healthy
embryo for Natasha,
resulting in Baby Zain.

(HLA) typing .
• This technology is generally employed by parents who have
a child affected by a particular disorder that could benefit
from some sort of human tissue transplant.
• For example, a child with leukemia who requires a bone
marrow transplant.
• In these cases, PGD has been employed as a modality to
ensure that the next child that the couple conceives will be
HLA compatible with their existing child with the given
illness.
• This practice is relatively uncommon but has generated
considerable debate regarding the ethics of HLA typing PGD

US scientists to create a lab human
sperm
• A team of Japanese scientists at
Kyoto University has successfully
created fertile eggs through the use
of stem cells. Their experiment
resulted in mice having healthy
babies. Taking the research forward
is Dr Renee Pera, of Stanford
University in California, who hopes
to soon create human sperm using
stem cells.

Lab-Made Eggs RaiseNew Fertility Options
Early-Stage Cells Used to Produce Healthy Mice;
Could the Dead Become Parents?
• Japanese scientists have made viable mouse
eggs in a laboratory dish, an advance that may
offer a new route for treating infertility in
people.
• The experiment completes a long-sought quest
in reproductive biology: to make sperm and
eggs in a lab dish. A year ago, the same core
group of scientists at Kyoto University created
healthy mouse sperm in the lab.
• In the latest experiment, the dish-created eggs
were fertilized with natural mouse sperm to
create healthy, fertile mice. The research
appears in the journal Science
145.
The technologies thatare coming
of age now and are visible on the
horizon have the potential to
expand the utilization of ART to
broad portions of society with and
without an infertility diagnosis.
